▎ 摘　　要

NOVELTY - Preparation of graphene-coated glass fiber composite material involves adding glass fiber into a muffle furnace, washing with acetone, hydrochloric acid and water, adding bovine serum albumin solution, drawing, obtaining bovine serum albumin-functionalized glass fiber, impregnating bovine serum albumin-functionalized glass fiber in graphite oxide dispersion, drying, obtaining graphite oxide-coated glass fiber and reducing the resultant material using reducing agent. USE - Preparation of graphene-coated glass fiber composite material used for electromagnetic shielding composite material. ADVANTAGE - The method provides graphene-coated glass fiber composite material having electroconductivity of 1-6 S/m as compared with electrically-insulating glass fibers, by a simple process.
